On average, Americans have lived in 2 places by the time they are 18 years old. Is this average less for college students? The 67 randomly selected college students who answered the survey question had lived in an average of 1.99 places by the time they were 18 years old. The standard deviation for the survey group was 0.3. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b.

The data suggest that the populaton mean is significantly less than 2 at a = 0.10, so there is statistically significant evidence to conclude that the population mean number of places that college students lived in by the time they were 18 years old is less than 2. O The data suggest that the sample mean is not significantly less than 2 at a = 0.10, so there is statistically insignificant evidence to conclude that the sample mean number of places that college students lived in by the time they were 18 years old is less than 1.99.
